Pi is 3.1415926... whether you know it or not. It's a constant. Just because you can't verify the answer without a calculator doesn't mean it's correct or incorrect. Next thing I know people are going to be saying pi=3, because that's easier to memorize.

got it right away, but still happy it had nothing to do with the number of letters in the numbers. I'm getting bored with those. I didn't read the hint until I read the comments. The hint redeemed it's entertainment value. Good job!
